The QUINT DC UPS is an intelligent modular solution that provides critical system-backup voltage to supply loads in the event of mains failure and indicates the operating and battery state. The battery management system (BMS) with IQ technology and a powerful battery charger ensures power reliability within a control system. Device variants are each available with industrial Ethernet network interfaces (EtherNet/IPTM, PROFINET, EtherCAT®) and USB or simply status contacts only. Networking enables the system to be monitored, conﬁgured, or shut down in a safe manner from any location.
